Abstract: Contextual data corresponding to previous search requests of a service provider's electronic catalog can be used to resolve voice-input search requests and present search results. Contextual data includes the previous search request that is input to a machine learning algorithm along with a present search request. The machine learning algorithm generates a score indicative of whether the present search request is a refinement of the previous search or a new search request. Once the search request is classified as a refinement or a new search, the search is processed to provide search results including available items from the service provider matching the search request.
